Structure-based design, synthesis and biochemical testing of novel and potent Smac peptido-mimetics
摘要:
Structure-based design, chemical synthesis and biochemical testing of a series of novel Smac peptido-mimetics as inhibitors of XIAP protein are described. The most potent compound, 6j, has a binding affinity (K-i value) of 24 nM to XIAP BIR3 protein and is 24 times more potent than the native Smac AVPI peptide. Further optimization of these potent Smac mimetics may ultimately lead to the development of a novel class of anticancer drugs for the treatment of human cancer by overcoming apoptosis-resistance of cancer cells through targeting the inhibitor of apoptosis proteins.

Although enantioconvergent alkyl-alkyl couplings of racemic electrophiles have been developed, there have been no reports of the corresponding reactions of racemic nucleophiles. Herein we describe Negishicross-couplings of racemic α-zincated N-Boc-pyrrolidine with unactivated secondary halides, thus providing a one-pot, catalytic asymmetric method for the synthesis of a range of 2-alkylpyrrolidines
Compounds that bind cellular IAPs (inhibitor of apoptosis proteins) are disclosed. The compounds are mimetics of the N-terminal tetrapeptide of IAP-binding proteins, such as Smac/DIABOLO, IIid. Grim and Reaper, which interact with a specific surface groove of IAP. Also disclosed are methods of using these compounds for therapeutic, diagnostic and assay purposes.
